• *NONE—disables any 802.11 encryption or security authentication mechanisms.
• WEP—a wireless encryption protocol that encrypts data frames on the wireless medium,
allowing for greater security in the wireless network. If WEP is used, you must configure each
handset to correspond with the encryption protocol configured in the access points. Select the
entries from the options below to enable the handset to acquire the system.
— Authentication—Select either Open System or Shared Key.
— WEP Enable/Disable—Select either Enable WEP or Disable WEP.
— Key Information—Configure the following:
– Default Key—Enter the key # specified for use by the handsets. This is 1 through 4.
– Key Length—Select either 40-bit or 128-bit depending on the key length specified for use at
this location.
– Key 1-4—Scroll to the key option that corresponds to the Default Key that you entered
above. Enter the encryption key as a sequence of hexadecimal characters. (Use the 2 and 3
keys to access hexadecimal digits A-F.)
— Rotation Secret—This is used for proprietary WEP key rotation. To determine whether this
feature is supported in your system, see your custom document.
• WPA2-PSK—The security features of WPA2-PSK are available and can be used if supported
by the access points in the facility. Select one of the following:
— Passphrase—enter a passphrase between 8 and 63 characters in length.
— Direct Entry—enter the 256-bit key code.
Attention: For information about whether WPA2-PSK is recommended for an AP, consult the
Configuration Note for the installed APs. Configure the recommended version on the AP and
select the corresponding option on the Admin menu.
• Cisco FSR—To provide the highest level of security without compromising voice quality on
Cisco Aironet WLAN APs, the Fast Secure Roaming (FSR) mechanism is implemented. FSR
is designed to minimize call interruptions for wireless handset users as they roam throughout a
facility. Existing Aironet 350, 1100, and 1200 APs can require a firmware upgrade to support
FSR. Cisco FSR requires advanced configuration of the Cisco access points at your site. See
the Cisco representative for detailed documentation about configuring your access points and
other required security services on your wired network. To configure Cisco FSR in the
wireless handset, you must enter a Radius Server username and password into each handset.
— Username—Enter a username that matches an entry on your Radius server. Usernames are
alphanumeric strings, and can be entered using the alphanumeric string entry technique.
— Password—Enter the password that corresponds to this Username.
• WPA-PSK—The security features of WPA-PSK are available and can be used if supported by
the access points in the facility. Select one of the following:
— Passphrase—enter a passphrase between 8 and 63 characters in length.
– 8-character passphrase—weak
– 20-character passphrase—minimum
– 20 to 30-character passphrase—recommended
– 63-character passphrase—very strong
— Direct Entry—enter the 256-bit key code.
